A prior analysis of patients undergoing laparotomy for ovarian malignancies at our institution revealed an increased rate of intra-abdominal collections using HA-CMC film during debulking surgery. The primary objective of the current study was to determine whether the use of HA-CMC is associated with the development of postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical malignancies.
We retrospectively identified all laparotomies performed for these malignancies from 3/1/05 to 12/31/07. We identified cases involving the use of HA-CMC via billing records and operative reports. Intra-abdominal collections were defined as localized intraperitoneal fluid accumulations in the absence of re-accumulating ascites. We noted incidences of intra-abdominal collections, as well as other complications. Appropriate statistical tests were applied using SPSS 15.0.
We identified 169 laparotomies in which HA-CMC was used and 347 in which HA-CMC was not used. The following were statistically similar in both cohorts: age, body mass index (BMI), primary site, surgery for recurrent disease, prior intraperitoneal surgery, and extent of current surgery. Intra-abdominal collections were seen in 6 (3.6%) of 169 HA-CMC cases compared to 10 (2.9%) of 347 non-HA-CMC cases (p=0.7). The rate of infected collections was similar in both groups (1.2% vs. 1.4%). In the subgroup that underwent tumor debulking, intra-abdominal collections were seen in 3 (11.5%) of 26 HA-CMC cases compared to 2 (5.4%) of 37 non-HA-CMC cases (p=0.6).
HA-CMC use does not appear to be associated with postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical cancer.

ABSTRACT: Hyaluronic acid is a prognostic factor in ovarian cancers. It is also a component of Hyaluronic Acid-Carboxymethyl Cellulose (HA-CMC) barrier, an anti-adhesion membrane widely used during abdominal surgeries in particular for ovarian carcinosis. 70% of patients who undergo ovarian surgery will relapse due to the persistence of cancer cells. This study's objective was to determine the oncological risk from use of this material, in the presence of residual disease, despite the benefit gained by it decreasing post-surgical adhesions in order to provide an unambiguous assessment of its appropriateness for use in ovarian surgical management.
We assessed the effects of HA-CMC barrier on the in vitro proliferation of human ovarian tumor cell lines (OVCAR-3, IGROV-1 and SKOV-3). We next evaluated, in vivo in nude mice, the capacity of this biomaterial to regulate the tumor progression of subcutaneous and intraperitoneal models of ovarian tumor xenografts.
We showed that HA-CMC barrier does not increase in vitro proliferation of ovarian cancer cell lines compared to control. In vivo, HA-CMC barrier presence with subcutaneous xenografts induced neither an increase in tumor volume nor cell proliferation (Ki67 and mitotic index). With the exception of an increased murine carcinosis score in peritoneum, the presence of HA-CMC barrier with intraperitoneal xenografts modified neither macro nor microscopic tumor growth. Finally, protein analysis of survival (Akt), proliferation (ERK) and adhesion (FAK) pathways highlighted no activation on the xenografts imputable to HA-CMC barrier.
For the most part, our results support the lack of tumor progression activation due to HA-CMC barrier. We conclude that the benefits gained from using HA-CMC barrier membrane during ovarian cancer surgeries seem to outweigh the potential oncological risks.

ABSTRACT: Background and Objectives: Adhesion of middle ear and mastoid cavity after mastoidectomy represents a potential source of surgical failure. GUARDIX-SL®, absorbable anti-adhesive material, which is composed of sodium hyaluronate and sodium carboxymethyl cellulose, is an effective agent that widely used as a surgical adjuvant to decrease adhesion in the surgery. Therefore, we evaluated the clinical efficacy of the GUARDIX-SL® for the prevention of adhesion after mastoidectomy. Subjects and Methods: This study was randomized and double-blinded. Conventional intact canal wall mastoidectomy was conducted in both control (n=14) and study group (n=10). To avoid bias because of different surgeons, we only included patients who were operated on by one surgeon. In the study group, 1.5 g GUARDIX-SL® was applied in the mastoid cavity at the end of mastoidectomy. To evaluate anti-adhesive effect of GUARDIX-SL®, the volume of aerated area in the mastoid cavity was calculated and compared with temporal bone computed tomography performed at preoperatively and postoperatively. Besides, to assess the success of operation, pure tone audiometry was also performed at preoperatively and postoperatively. Results: The volume of aerated area of mastoid cavity after mastoidectomy was more increased in GUARDIX-SL® group, but was not statistically significant in the GUARDIX-SL® group than the control. And all results of pure tone audiometry satisfied the criteria of successful operation which has been suggested by Otological Society of Korea. Conclusion: The results suggest that GUARDIX-SL® may be an efficacious and safe material in decreasing the incidence of adhesion after mastoidectomy.

ABSTRACT: Postoperative adhesions after abdominopelvic surgery can be prevented with the use of mechanical barriers such as Seprafilm membranes. However, this procedure is not without complications. Herein are reported 2 cases of Seprafilm-associated sterile peritonitis after gynecologic surgical procedures. Both patients had symptoms that mimicked intraabdominal abscess formation soon after the initial surgery (1 patient had delivered via cesarean section, and the other had undergone total hysterectomy because of adenomyosis). However, laparoscopic examinations in these 2 patients revealed only gel-like hydrated Seprafilm without evidence of infection. Symptoms resolved after the abdominal cavity was thoroughly irrigated and the Seprafilm residue was completely removed. Both patients had an uneventful recovery. Previous reports suggested that Seprafilm-related complications were most commonly observed in patients who underwent gynecologic debulking surgery because Seprafilm might react with the large area of the injured peritoneum and induce a strong inflammatory response. However, our experience showed that such complications could also be observed in patients who underwent nondebulking surgery. A laparoscopic approach should be considered the treatment of choice under these conditions to avoid unnecessary laparotomy.
